Sample Audio from the Official USB Court Reporter Microphone



I am a licensed court reporter for both Utah and California.  I am currently a working reporter in the State of Utah.  I can't speak highly enough of the Martel products and their ongoing support for court reporters who purchase their products. I purchased both the hand held recorder and the USB external microphone.  Was it an expensive investment?  Compared to the cost to purchase my writer and Case Catalyst software, NO.  I use the hand held recorder as my backup.  The USB external mike is synced to my software.  Fellow reporters:  If you don't have a Martel product and you feel you have "the best quality" external mike and recording equipment, I can tell you without hesitation that you are wrong.  I tried a cheapie external mike that I purchased from Amazon, and I was assured it was great quality.  There is NO COMPARISON to the quality of the Martel products.  NONE.  Any time I need help, the staff at Martel are amazing.  They go out of their way to make sure everything is working properly, and their recording equipment is designed especially for the court reporting industry.  I can't speak highly enough of their products and their support.  Do yourself and your work a favor -- get their recording device and external mike.  You won't regret it.

The HGMUSB has improved audio quality and increased the pickup range to over 6 times that of an average court reporting microphone. During the last couple of years, major laptop makers have continually lowered the standards of built-in sound cards, resulting in sound quality problems for our reporters. If your career is counting on the right equipment, you can't afford to be without an HGMUSB Audio Sync microphone!

The HGMUSB enhances audio quality and pickup range, surpassing average court reporting microphones, a significant improvement over laptop makers' lowered sound card standards, making it essential for reporters' careers.
There are 2 Questions to ask when buying a Court Reporting Microphone:

Is this microphone made in America and does this microphone use an expensive Hearing Aid ultra-sensitive IC chip?

The Martel HGM-USB is exclusively made in America and does use a very expensive Hearing AID ultra-sensitive IC chip + Noise Canceling technology made specifically for court reporting.

Notice: Official HGMUSB microphones are sold exclusively through authorized dealers.
Accept only the real HGMUSB, it is imprinted on the unit. 

NEW Windows 10 FEATURE - Live Monitoring, you now can listen through your headsets with the HGMUSB even if you are not recording. Boosting your own hearing by 351%.

The HGMUSB Court Reporter USB Microphone has a GREEN LIGHT indicator light that tells you that your microphone is working and recording. This is the only microphone in the world that has a recording indicator light.

The USB microphone goes around the sound card, so if you have a poor sound card it does not matter. 100% digital audio replication. Saving precious processing power for your court reporting software. Martel spent years developing a solution that exceeds the pickup voice range of the HGM-1. The HGMUSB has a pick-up range of up to 133 Feet (adjustable).

The Martel HGMUSB Digital court reporter microphone has a very special performance advantage. Since the HGMUSB microphone is already sending a digital signal, your laptop won't need to use its Intel processor to change the audio signal to a digital signal. This will save precious computer resources and make your computer faster and more reliable. Especially if you are a real-time reporter. Our microphone is compatible with USB 3.0.

Superior Court Reporters in Tucson Testimonial

Jason was professional and was great to work with in ordering the Court Reporter microphones for many Superior Court Reporters in Tucson. This microphone will be an excellent tool for us here. I'm sure we will be back to work with Jason and Martel again. Thank you for working with us, Jason.

    Love this USB Court Reporter microphone.  It works great in depositions and well in court, especially with the microphone stand (Included).  No battery headaches (do I have an extra battery with me) or battery ulcers (is the battery going to go out during this job that is killing me).  I can determine from looking at a popup on my software that the sound is coming through. (The HGMUSB microphone has a heads up Green light indicator on it that tells you it is working) This is my second HiGain court reporter Microphone.   I love it and am getting another.

    Great USB Court Reporter Microphone

    Posted by Lisa S. CSR Court Reporter on 16th Jul 2019

    The best a Court Reporter can buy

    Posted by Nadia V. on 20th Mar 2019

    I've been through a lot of microphones in my career, even all the new ones being sold on the internet. I bought a very expensive $500 mic from New Jersey and it was terrible. Imagine my surprise when I couldn't return it, what a mistake. There are other companies dedicated to court reporting that sell mics made for us, like the HGMUSB from Martel. It's not a Chinese knockoff like you see everywhere.

    USB Microphone in court

    Posted by Laura W. Official Court Repoter on 11th Dec 2018

    I want to thank you, Martel, for always coming thru. I'm an official in Superior court and was desperate to find a stand for my mic. I tried everywhere even Amazon. No luck. Then I thought what about Martel, which I had ordered my digital recorder from. Well, you had exactly what I needed and it came in the mail a few days later. I'm up and running with my new stand. Can't thank you enough from all us Court Reporters around the country. Please make sure the Big Bosses get this review. I always highly recommend your products\microphones to every court reporter I know that needs help. Much appreciated and Merry Xmas to all of your staff at Martel.

    My audiosync sounds crystal clear

    Posted by Jennifer A. on 23rd Oct 2018

    I was shocked how clear my stenograph recordings sounded. This is the best court reporter microphone, I even heard. I hear my judge sits around 18 feet away from me perfectly now. So worth the money. This is the only USB microphone I will ever buy for court reporting.
